Guest: Find the present value of $50,000 invested for 8 years at 3 percent compounded semi annually
If $50000 is invested today at 3% (pa?) compounded semi annually and left there for 8 years.,
The present value would be $50000 because that is what present value means, it is the 'today' value.
If you really wanted the future value then you will have to post again
or
If $50000 is what the money will grow to (future value) and you want present value'll still need to post again
